I guess i better start looking into that as well i will ket you know if i find 
anything. Could you tell me where i can access those articles? 
Thanks.

Today I read 2 articles on the danger of toxic materials being released from 
LED lights.  A colleague told me of another article as well.  
 
Does anyone have any information on the downside of LED lighting either 
therapeutically or conventionally?
Thanks.

Re: CS>LEDs

Hi PT.

That article, only one I could find , seems to be scaremongering. They do not 
mention
quantities per 'bulb'. And they do not give the science behind it. And the how 
do you break an
led? and then how is the metal contamination released to the atmosphere if it 
is incorporated
into the electronics of the led? Versus CFLs where the contaminants are a gas 
or a powder
which are released if the glass cracks.

It seems to be an Anti_led emotional scare marketing ploy.

OK ,
Tony

Re: CS>LEDs

[Christina Mattson]

PT, I have the same thoughts as Tony as far as scare mongering.  None of these 
address the therapeutic use of  them, regular light strands have lead in them 
too, so you wash your hands after handling them or wear gloves.  Now as far as 
the blue and white color intensity harming children's eye's I don't think it 
would be a good idea to use them around your house if your child likes to stare 
at them. In my experience being around children with sensory issues sometimes 
they like to stare at the red but it makes no mention of the red harming the 
cornea of children's eyes, besides no decent parent is going to allow that. 
Once i was researching night blindness and read an article where people were 
disputing the blue LED's used on car headlights and appliances because it was 
bothersome but only some people had a problem with that. I have light 
sensitivity issues but have never really been bothered by it.
Now as far as the larger holiday light strands, the bulbs are usually covered 
with a plastic bezel that looks like it's part of the bulb but the bulb is 
underneath.
There are lots of holes in those articles. If i find any discrepancy about 
the safety of increasing cellular energy with them than i will be sure to share 
it with you.

PT, I have the same thoughts as Tony as far as scare mongering.  None of these 
address the therapeutic use of  them, regular light strands have lead in them 
too, so you wash your hands after handling them or wear gloves.  Now as far as 
the blue and white color intensity harming children's eye's I don't think it 
would be a good idea to use them around your house if your child likes to stare 
at them. In my experience being around children with sensory issues sometimes 
they like to stare at the red but it makes no mention of the red harming the 
cornea of children's eyes, besides no decent parent is going to allow that. 
Once i was researching night blindness and read an article where people were 
disputing the blue LED's used on car headlights and appliances because it was 
bothersome but only some people had a problem with that. I have light 
sensitivity issues but have never really been bothered by it.
Now as far as the larger holiday light strands, the bulbs are usually covered

Re: CS>LEDs

PT, it's not coming back to me like usual when i send but here are the links to 
two of them and i'll work on the file from Phillips.
Tina

You will find detailed information if you go to www.Answers.com and in the Ask 
a question box right at the top type in "light-emitting diode" this tells about 
the different types, what they are made of the color and wavelength, voltage, 
semiconductor materials. The difference between Oranic light-emitting diodes, 
Quantum dot LEDs, SuperFlux LED's. LED's and the environment, the economy, etc, 
etc. A wealth and an overload of info all at the same time.
For another one go to www.elixa.com when you get there type "Healing with 
single frequency light" into the search bar. Click on the first selection from 
the list. These are two that i had in my file but i figured it would be easier 
this way. The other is attached above.

The leds are cool so there is no burn.

for some reason V doesn't have direct linking to the godzill page from the
rest of the LED pages.  from the LED area you'd never know it's there.  now
i see it's over on a completely different domain/website.  wouldn't show up
in google either weird, it used to i think.

Re: CS> LEDs & arthritis: COMMENT

I would remind list members that if one is investigating the use of LED bulbs/arrays for
 circulation improvement and/or topical pathogen controlwe have found that the red spectrum elements in the 660 to 680 nanometer range are MUCH superior those in other ranges.  They do not cost any more than other colored...or clear bulbs.but are immensely more effective at circulation improvement.  At least that has been our experience.

Re: CS> LEDs & arthritis: COMMENT

[kayedoe]

Interesting thread.

I picked up something similar to the flashlight you described at
Murray's auto parts store, about a year ago. It has RED LED's in rows
along the length of the flashlight and can be made to pulse (on/off)
or run in constant mode. It also has powerful magnets on the lamp end
so it can be set on the top of the car for a trouble beacon. I think
it was only 19.00.

Last year at Christmas time when family was over, my granddaughter
picked up some foam painting pads I had by my computer. I immediately
said put that down those are for a medical device I want to put
together.

Well, probably don't have to tell you everyone burst out
laughing...LOL My oldest daughter said Oh come on now mom you got
to be kidding! She thought I was being ridiculous. Naturally I replied
NO, I'm not kidding, with a straight face and began to educate her.

She wasn't interested, but some day she may be :o)

Geeze, now my flashlight will fall into the don't touch category. How funny!

That is correct. Which left me wondering how much "red" there is in a 
white LED. This seems to answer that:

Apparently not a lot.  I believe that much of the reason that the red 
works so much better than the other colors is that the shorter 
wavelengths are absorbed before they get much penetration.  If you shine 
a white light on your hand, what you see coming through will be red.

Now this sounds like a great idea. Did you just shine the flashlight

at your shoulder for awhile? And is there a link somewhere to link to

for more info in using LED's ?

I have heard blue in the 400-500nm range is effective for acne and other skin 
issues. A famous laser company is selling a 405nm laser specifically for acne 
treatment. I'm wondering if red is just as good?

Re: CS> LEDs & arthritis: COMMENT

[Clayton Family]

Thanks for the clarification.   This makes me think of my grandma using 
infrared for her arthritic hands, so she could quilt.  I am looking up 
the LED s.  --Kathryn

I looked at the graph, and was not sure how to interpret it.   There 
was a spike in the graph between 500 and 600nm.


But when I was a kid, I thought the flashlight was red because I have 
red blood!   LOL  --Kathryn

Someone asked to forward Brooks' comments on LEDs.
